Floral emblem of Wales (8)
I believe the answer is:
daffodil
'floral emblem of wales' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for daffodil that I've seen before include "Lent lily" , "Yellow bloom" , "Popular yellow flower of spring - ask Wordsworth" , "Floral emblem of Wales" , "Type of 24 across" .)
